Technical Field
[0001] This utility model relates to the field of heaters, and in particular to a heater with an opening and closing structure. Background Technology
[0002] A heater is an electrical appliance used for indoor heating. Heaters provide warmth through electric heating or radiant heating. The panel components of heaters are generally made of polyoxymethylene (POM), which has high strength, wear resistance, toughness, fatigue resistance and creep resistance, making it suitable for harsh environments.
[0003] Existing heaters typically have a light panel installed on their panel. This light panel provides basic indoor lighting, and in some designs, it can illuminate the area around the heater to prevent accidents caused by insufficient light while heating. The light panel is usually installed using a snap-fit method. However, to achieve its lighting function, the light panel has numerous electrical components connected to the panel. Therefore, each time the light panel is installed or repaired, it requires manual handling to operate and repair the internal components. This process is cumbersome, and since the heater is installed in the ceiling, operators need to climb, which also increases the risk of installation hazards. To address these issues, a solution is proposed below. Utility Model Content
[0004] The purpose of this invention is to provide a heater with an opening and closing structure to solve the problems mentioned in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A heater with an opening and closing structure includes a panel body and a lamp plate installed at the bottom of the panel body. Two device boxes are symmetrically installed at the bottom of the panel body. A stepper motor is installed on the side wall of each of the two device boxes. The output shaft of the stepper motor passes through the side wall of the device box. A drive gear is rotatably arranged inside the device box. The output shaft of the stepper motor is fixedly connected to the drive gear. A sector gear is also rotatably arranged inside the device box. A limiting structure is provided between the sector gear and the device box. The sector gear meshes with the drive gear. A positioning component connected to the sector gear is also provided on the side wall of the device box. An active rod is installed at one end of the sector gear. The end of the active rod away from the sector gear is hinged to the top of the lamp plate. A support component for supporting the lamp plate is also provided at the end of the device box away from the drive gear.
[0007] Preferably, the limiting structure includes two ball bearings. Grooves are provided on both the sector gear and the inner wall of the device box. The two ball bearings are respectively installed in the two grooves. The length of the ball bearing on the sector gear is longer than the length of the groove. Both ends of the ball bearing protrude from the groove. One end of the ball bearing on the device box is located outside the groove.
[0008] Preferably, the positioning assembly includes a bushing, a pin, a lever, and a micro switch. The sector gear has a mounting hole in its middle, the bushing is installed in the mounting hole, the bushing and the sector gear are coaxially arranged, the pin is installed inside the bushing, one end of the bushing is located outside the device box, the lever is installed on the outer wall of the bushing, and the micro switch is installed outside the device box, corresponding to the lever.
[0009] Preferably, the support assembly includes a connecting rod, a torsion spring, and a driven rod. The connecting rod is installed inside the device box, the torsion spring is sleeved on the outside of the connecting rod, one end of the driven rod is hinged to the lamp panel, and the other end of the driven rod is rotatably disposed inside the device box.

[0022] See Figures 1 to 8 As shown, a heater with an opening and closing structure includes a panel body 1 and a light panel 2 installed at the bottom of the panel body 1. Two device boxes 3 are symmetrically installed at the bottom of the panel body 1, and a protective cover 12 corresponding to the device boxes 3 is installed on the top of the panel body 1. Stepper motors 4 are installed on the side walls of both device boxes 3. When it is necessary to open the light panel 2, the control button at the bottom of the panel body 1 can be pressed, and the stepper motors 4 will start. The output shaft of the stepper motor 4 passes through the side wall of the device box 3. A drive gear 5 is rotatably installed inside the device box 3. The output shaft of the stepper motor 4 is connected to the drive gear 5. The drive gear 5 is fixedly connected, and the stepper motor 4 drives the drive gear 5 to rotate. Inside the device box 3, a sector gear 6 is also rotatably installed. The sector gear 6 meshes with the drive gear 5. The drive gear 5 can drive the meshing sector gear 6 to rotate. One end of the sector gear 6 is equipped with an active rod 9. The end of the active rod 9 away from the sector gear 6 is hinged to the top of the lamp panel 2. The sector gear 6 can pull the active rod 9 to swing. Through the cooperation between the drive gear 5, the sector gear 6 and the active rod 9, the rocker mechanism is realized, realizing the opening and closing of the lamp panel 2.
[0023] The end of the equipment box 3 away from the drive gear 5 is also provided with a support component 10 for supporting the lamp plate 2. By setting it in the support component 10, the lamp plate 2 can be better supported, preventing the lamp plate 2 from shifting when it is opened, which would cause unevenness during subsequent recycling.
[0024] The support assembly 10 includes a connecting rod 101, a torsion spring 102, and a driven rod 103. The connecting rod 101 is installed inside the equipment box 3, and the torsion spring 102 is sleeved on the outside of the connecting rod 101. One end of the driven rod 103 is hinged to the lamp plate 2, and the other end of the driven rod 103 is rotatably disposed inside the equipment box 3. Both the connecting rod 101 and the torsion spring 102 are disposed inside the driven rod 103, and one end of the torsion spring 102 is connected to the driven rod 103. The sector gear 6 pushes the lamp plate 2 to open and close through the driving rod 9. During the opening and closing process, the lamp plate 2 pushes... The driven rod rotates, supporting the lamp panel 2 via the driven rod 103. During rotation, the driven rod 103 also deforms the torsion spring 102, generating elastic force. When the lamp panel 2 retracts, this elastic force, generated by the torsion spring 102, applies a restoring force to the lamp panel 2 via the driven rod 103, reducing the load on the stepper motor 4. The torsion spring 102 also prevents the driven rod 103 from suddenly dropping due to gravity when the lamp panel 2 opens, resulting in a smoother and more stable opening of the lamp panel 2. Compared to traditional support methods, this support assembly significantly reduces the failure rate during lamp panel opening and closing, making the opening of the lamp panel 2 smoother and more stable.
[0025] The device box 3 is also equipped with two limiting baffles 11. The two limiting baffles 11 correspond to the sector gear 6 and the driven rod 103 respectively. By setting the limiting baffles 11, the rotation of the driving rod 9 and the driven rod 103 can be limited.
[0026] A limiting structure 7 is also provided between the sector gear 6 and the equipment box 3. By installing the limiting structure 7 between the sector gear 6 and the equipment box 3, the sector gear 6 is prevented from making large-area contact with the side wall of the equipment box 3 when it rotates, thereby generating friction.
[0027] The limiting structure 7 includes two ball bearings 71. Grooves 72 are formed on both the sector gear 6 and the inner wall of the equipment box 3. The two ball bearings 71 are respectively installed in the two grooves 72. The length of the ball bearing 71 on the sector gear 6 is longer than the length of the groove 72, and both ends of the ball bearing 71 protrude from the groove 72. One end of the ball bearing 71 on the equipment box 3 is located outside the groove 72. By installing the ball bearings 71 on the sector gear 6, the ball bearings 71 can separate the sector gear 6 from the inner wall of the equipment box 3, preventing the sector gear 6 from being pulled away during rotation. When the oscillating gear 6 contacts the inner wall of the device box 3, the continuous rotation of the sector gear 6 causes the ball bearing 71 on the sector gear 6 to contact the ball bearing 71 on the device box 3. The stepper motor 4 continuously outputs power, causing the sector gear 6 to continue rotating, causing the two ball bearings 71 to squeeze and deform against each other. The ball bearing 71 on the sector gear 6 will rotate to the other side of the ball bearing 71 on the device box 3. When the stepper motor 4 is turned off, the two ball bearings 71 can achieve a locking function, reducing the pulling force of the light panel 2 on the stepper motor 4.
[0028] The side wall of the equipment box 3 is also provided with a positioning component 8 connected to the sector gear 6. By setting the positioning component 8, the rotation positioning of the sector gear 6 is more accurate, preventing the sector gear 6 from not rotating into position, which would cause the lamp panel 2 to not open or close properly.
[0029] The positioning assembly 8 includes a bushing 81, a pin 82, a lever 83, and a micro switch 84. A mounting hole is provided in the middle of the sector gear 6, and the bushing 81 is installed inside the mounting hole, coaxially with the sector gear 6. The pin 82 is installed inside the bushing 81, with one end of the bushing 81 located outside the equipment box 3. The lever 83 is installed on the outer wall of the bushing 81, and the micro switch 84 is installed outside the equipment box 3, corresponding to the lever 83. When the sector gear 6 rotates, it drives the bushing 81 to rotate, which in turn drives the lever 83 to rotate. The continuous rotation of component 3 causes the toggle 83 to contact the micro switch 84, which in turn closes the micro switch 84. When the micro switch 84 is closed, it sends a signal to the stepper motor 4, causing it to shut down and stop rotating. The sector gear 6 also stops rotating, and the lamp panel 2 opens to the designated position. The stepper motor 4 is also connected to an encoder. When the lamp panel 2 is repaired and needs to be reset, the stepper motor 4 can be restarted to return it to its original position, thus resetting the lamp panel 2. This design of the positioning component 8 not only improves the accuracy of the lamp panel 2's opening and closing but also reduces jamming during the process, extending the lifespan of the device and improving the overall performance of the heater.
[0030] Working principle: When the lamp panel 2 needs to be repaired, the stepper motor 4 can be started first. The stepper motor 4 will drive the drive gear 5 to rotate. Through the cooperation between the drive gear 5 and the sector gear 6, the active rod 9 will be driven to rotate, thereby forming a rocker mechanism to realize the automatic opening of the lamp panel 2. Through the added support component 10, the lamp panel 2 can be better supported by the driven rod 103 during the opening and closing process. The torsion spring 102 set on the driven rod 103 can also apply a rebound force to the lamp panel 2 through the driven rod 103, reducing the load on the stepper motor 4. During the rotation of the sector gear 6, it will drive the positioning component 8 to rotate synchronously. The bushing 81 in the positioning component 8 is coaxially set with the sector gear 6. When the bushing 81 rotates with the sector gear 6, the toggle block 83 installed on its outer wall also rotates together. When the toggle switch 83 rotates to contact the micro switch 84 and triggers the micro switch 84, the micro switch 84 sends a signal to the stepper motor 4, controlling the stepper motor 4 to stop rotating, thereby allowing the lamp panel 2 to accurately open to the designated position with high positioning accuracy. This precise positioning, working in conjunction with other structures, effectively improves the stability and reliability of the heater lamp panel's opening and closing, reduces malfunctions caused by incomplete opening and closing, extends the equipment's service life, and provides users with a more convenient and stable user experience.
